FEED-WATER REGULATOR FOR BOILERS.

ESPECIFIOATION forming part of Letters Patent No. 608,568, dated August9, 1898.

Application filed May16,1896. Serial 110,591,819. (No model.) Patentedin England June 8, 1895, 1\ o.11,253; in Germany April 12, 1896, No.91,153; in PPdl10GA 1'fl1'7,189G,NO-255,614:l]l Italy June 30, 1896,1l0. 81/291; in Denmark December 11, 1896, N0. 874, and in AustriaFebruary 9,1897, N0. Q7/440- To aZZ whom it may concern.-

Be it known that I, ALFRED BLEOHYNDEN, a subject of the Queen of GreatBritain and Ireland, and a resident of l3arrow-in-Furness, England, haveinvented certain new and useful Feed-Water Regulators for Boilers, ofwhich the following is a specification.

The invention has been patented in Great Britain, o. 11,253, dated June8, 1895; in France, No. 255,611, dated April 17, 1896; in Germany, No.91,153, dated April 12, 1896; in Denmark, No. 874, dated December 11,1896; in Italy, No. 81/291, dated June 30, 1896, and in Austria, No.47/4 10, dated February 0, 1897.

This invention relates to apparatus for regulating the admission offeed-water to boilers in which a feedadmission valve is actuated by afloat on the surface of the water in such boilers.

The invention consists in the combination and arrangement of elementshereinafter specified.

In the drawings hereto annexed, Figure 1 is a side view, and Fig. 2 anend view, showin g the general arrangement of a feed-admission valveaccording to this invention as applied to the upper chamber of awater-tube boiler. Fig. 23 is a sectional elevation of the valve and itsseat. Fig. 1 is an end view. Fig. 5 is a section on line A B, Fig. 3.Figs. 6 and 7 are details. Fig. 8 isasectional view of a modification.Figs. 9, 10, 11, and 12 are details of the same. Fig. 13 is a sectionalview of another modification. Fig. 14C is a sectional view of anothermodification. Figs. 15 and 10 are detail views relating thereto, andFig. 17 a sectional view of another modiiied form of valve and itsseating.

A denotes the feed-admission valve, B its spindle, and G a spindle bywhich the position of its seating is adjusted. D is the float, E thefloat-lever, and F is a counterpoisc thereon. G is the feed-inlet, and11 its out let, J being the shell of the boiler. Three water-levels areindicated in Fig. 1, the positions of the lioatD corresponding withthese levels being dotted in the iigure. To protect it from the effectof violent ebullition, the .lloat D is located in a chamber D, havingper forations. The chest A has inlet and outlet ports G H, respectively.Within the chest A is a sleeve a, upon one end of which the valve 1) isseated. The valve 1) is carried by the spindle 13, which is coupled tothe float-lever. The sleeve a is movable longitudinally and is caused toapproach or recede from the valve 1) by a screwed red O passing througha gland c and screwed bracket 0' outside of the boiler, a hand-lever cand lock-nut c being mounted on the rod 0. The sleeve to has ports a inpermanent communication with the valvechest A and feed-inlet G. Ports ain the chest A admit boiler-pressure in front of the sleeve a, andsimilar ports Z) admit it in front of the piston Z1 on the valve-spindle13, thus preserving approximate equilibrium in these parts. Fig. 6 showsconnection of the spindle C to the sleeve a, and Fig. 7 is an end viewof the gland o and bracket 0. As the sleeve a is caused to approach orrecede from the valve 1) by turning the hand-lever 0 the position of thefloat-lever E, Fig. 1, atwhich it closes the valve is changed, andconsequently the level of water in the boiler at which feedavater ispermitted to enter or is cut olf is determined.

111 the following modifications of the apparatus above described like orequivalent parts are lettered alike in the drawings, their functionsbeing similar to the parts correspondingly lettered in Figs. 3 to 7.

- In Fig. 8 boiler pressure within the chest A is exerted on bothvalves 1) Z), the piston b merely acting as a guide to the spindle B.The port a permits a free inflow of feed-water when the sleeve (4 isdrawn back sufiiciently to uncover it, the valves 7) I) being preventedfrom following the sleeve (0 by the stops l3 abutting against the end ofthe float lever connecting-rod. c is an index-plate on which theindex-wheel 0 indicates the position of the sleeve a, the distance no 2representing regulated inflow, and .e' the position of sleeve a whenthere is a free inflow through the port a Fig. 9 is an end view of Fig.8. Fig. 11 shows connection of sleeve a and spindle C, and Fig. 12 is anend view of gland c and bracket 0.

In Fig. the sleeve a is adjustable with in the boiler by a lug a andnuts or on the screwed stud a, the operation of the valve beingotherwise identical with those above described.

In Fig. 14 the sleeve 0. and valve 1) have rotary movement in place oflongitudinal movement. The lever B mounted on the valvespindle B, may becoupled to the float-lever E, Fig. 1, or the float-lever E may bemounted directly on the spindle B. The lever O, mounted on the sleeve a,may be controlled by a hand operating connection similar to thosealready described, by which it may be adjusted. From the inlet G asemi-annular passage G leads around the sleeve to. Communication betweenthe passage G and the interior of the valve 1) exists by way of ports din the sleeve a and ports a in the valve b, the exit from b to the chestA and outlet H being by way of the ports 6'. As the sleeve a is movedcircumferentially in either direction the circumferential distance to betraveled by the valve 1) before a free passage through the ports d and eis established or cut off is varied. Consequently more or less travel isallowed to the float-lever E, Fig. 1, and thus the levels of water inthe boiler at which feedwater is permitted to enter or is cut off aredetermined. Fig. 15 is a cross-section of the valve, and Fig. 16 is anend View showing keep-plate K for securing the sleeve (4 and valve b inplace.

In Fig. 17 the hollow valve b and sleeve to are movable longitudinallyinstead of circumferentially, the operation of the valve being otherwiseidentical with that shown in Figs. 14 to 16.

Having now described this invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In apparatus for regulating the inflow of feed-water to a boiler, thecombination of a valve 1) operated by a float D on the surface of thewater in said boiler, with a valve-seating a which is capable oflongitudinal adjustment relatively to said valve by means of a screwedrod 0 working in a gland c and screwed bracket 0 on the shell J of saidboiler, as herein described.

2. In apparatus for regulating the inflow of feed-water to a boiler, thecombination of a valve 1) operated by a float D on the surface of thewater in said boiler, with a valve-seatin g Ct which is capable oflongitudinal adj ustment relatively to said valve, said seating beingprovided with a port a by which a free inflow of feed-water may takeplace when the seating ais withdrawn sufficiently to uncover it, thevalve 1) being prevented from following the seating (L by the stops B,as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ALFRED BLECHYNDEN.
